Thin client means no more cumbersome downloads of 30GB+ for the ethereum blockchain!

For more info on the thin client mode see FAQ.

TREZOR ONE support, long on the wishlist, is now a reality. Just plug in your TREZOR ONE and go from there. For more info on TREZOR ONE support see FAQ.

The ethereum testnet has been very unstable. This release changes the testnet chain to rinkeby hopefully making it more useful. NOTE: testnet is only supported in full node mode.

This is a major version upgrade so everyone will be prompted to review settings on first start.
